Ubuntu Security Notice 7019-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.

### Summary We discovered a DOM Clobbering vulnerability in Vite when building scripts to `cjs`/`iife`/`umd` output format. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. Note that, we have identified similar security issues in Webpack: https://github.com/webpack/webpack/security/advisories/GHSA-4vvj-4cpr-p986 ### Details **Backgrounds** DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering, here are some references: [1] https://scnps.co/papers/sp23_domclob.pdf [2] https://research.securitum.com/xss-in-amp4email-dom-clobbering/ **Gadg...

Cato CTRL (Cyber Threats Research Lab) has released its Q2 2024 Cato CTRL SASE Threat Report. The report highlights critical findings based on the analysis of a staggering 1.38 trillion network flows from more than 2,500 of Cato’s global customers, between April and June 2024. Key Insights from the Q2 2024 Cato CTRL SASE Threat Report The report is packed with unique insights that are based on

Red Hat OpenShift sandboxed containers, built on Kata Containers, now provide the additional capability to run confidential containers (CoCo). Confidential Containers are containers deployed within an isolated hardware enclave protecting data and code from privileged users such as cloud or cluster administrators. The CNCF Confidential Containers project is the foundation for the OpenShift CoCo solution. You can read more about the CNCF CoCo project in our previous blog What is the Confidential Containers project?Confidential Containers are available from OpenShift sandboxed containers release

Red Hat Security Advisory 2024-5982-03 - An update for linux-firmware is now available for Red Hat Enterprise Linux 7.7 Advanced Update Support. Issues addressed include a bypass vulnerability.

In recent investigations, Talos Incident Response has observed the BlackByte ransomware group using techniques that depart from their established tradecraft. Read the full analysis.

Confidential containers are containers deployed within a Trusted Execution Environment (TEE), which allows you to protect your application code and secrets when deployed in untrusted environments. In our previous articles, we introduced the Red Hat OpenShift confidential containers (CoCo) solution and relevant use cases. We demonstrated how components of the CoCo solution, spread across trusted and untrusted environments, including confidential virtual machine (CVM), guest components, TEEs, Confidential compute attestation operator, Trustee agents, and more, work together as part of the soluti

Ubuntu Security Notice 6952-2 - Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose sensitive information or possibly execute arbitrary code in the trusted execution environment. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Microsoft on Tuesday shipped fixes to address a total of 90 security flaws, including 10 zero-days, of which six have come under active exploitation in the wild. Of the 90 bugs, seven are rated Critical, 79 are rated Important, and one is rated Moderate in severity. This is also in addition to 36 vulnerabilities that the tech giant resolved in its Edge browser since last month. The Patch Tuesday
